Hi Caleb,
Thank you for your query. You can base your grant calculations based on HDB’s site here (https://www.hdb.gov.sg/residential/buying-a-flat/flat-and-grant-eligibility/couples-and-families/cpf-housing-grants-for-resale-flats-families).
You’re right, based on the total income of S$6.7k, the EHG will be S$25k. And the PHG will be S$20k given that it’s within 4km of your parents’ house.
However, note that you won’t be able to get the maximum S$80k for the Family Grant, as it is based on resident status and flat type. As a SC/PR household, the Family Grant you can get is S$70k if you’re buying 2-room to 4-room flat, or S$40k if you’re buying 5-room or bigger.
It is best to check with HDB on the actual grant amount.
Hope this helps and good luck!
